Going back to the moan about floor singers just reading their songs from folders or i-phones I wrote the following song. Another thing that annoyed me once when a booked guest got in a tizz because he couldn't get a phone signal and needed it to access his setlist.
The song is sung to the tune Nic Jones uses for "Barrack Stree" or Noel Murphy for "Paddy & The Bricks"

Learn the song!

A man came to a folk club with a fine Martin guitar
A music stand with a little light. Professional! A star!
He opened up his folder at page number 62
And then he sang the same Tom Paxton song he always seems to do.

And it only had three verses, and it only had three chords
So come on guys, learn the song! The music and the words!

Then I saw another bloke, just the other day
Put his i-pad on the mic stand, and he began to play
He stopped, he blushed, he knew he?d lost the audience affection
Why have you stopped? He cried ?I?ve lost my internet connection!?

Chorus

In this modern age of apps, many sights you see
At an open mic a singer said ?Please accompany me?
The guitarist got his phone out to help him play the chords
The singer had his own phone out to remind him of the words!

Chorus

How difficult is it to just to learn a simple basic song?
Carthy and Dylan often sing ones thirty verses long!
It?s not jazz, it?s not prog rock, the chords are pretty easy
Is it just playing in public that makes folk singers queasy?

Chorus
